10.2 Globbing

The archetypal use of wildcards is for matching against the files in a
directory, and making a list of all the matches. This is called
globbing.

You could do this using fnmatch, by reading the directory entries
one by one and testing each one with fnmatch. But that would be
slow (and complex, since you would have to handle subdirectories by
hand).

The library provides a function glob to make this particular use
of wildcards convenient. glob and the other symbols in this
section are declared in glob.h.
